1, precision bearing tolerance: domestic bearing size deviation and rotation accuracy though and import bearing is already very close. But with import precision double row bearings in discrete SKF, there is still a gap in degrees. Foreign had begun to research and application "cannot repeat beat" such fine rotation accuracy index and China in the studies of this or blank.

2, the vibration and noise and different sound, Japan has launched mute and the mute double row bearing, and China bearing vibration extreme level and Japan bearings, compared to more than 10 dB difference commonly.

3, in the life and reliability, deep groove ball bearing, for example, foreign brand products for the life of the calculation of the general life more than 8 times (up to 30 times above), reliability of 98% (or pursuit and hosts, life), and the life of Chinese bearing in general only the service life of the calculation for 3 to 5 times, reliability for about 96%.

4, in high speed performance, foreign brand products, value of up to 4 by 106 mm r/min, and China is only 2 by bearing 106 mm r/min.
